Ethylcellulose bụ polima a na-ejikarị eme ihe nke ọma, nke a na-ejikwa n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere ọgwụ, ihe mkpuchi, ihe mgbakwụnye na nri. A na-ahazi ọkwa dị iche iche nke ethylcellulose iji mezuo ihe achọrọ kpọmkwem n'ihe gbasara viscosity, ibu molekul na ihe ndị ọzọ.
Nhazi nke ethyl cellulose:
Ethylcellulose bụ ihe sitere na cellulose, polima eke a na-ahụ na mgbidi mkpụrụ ndụ osisi. Ime ka cellulose dị ọcha gụnyere iwebata otu ethyl n'ime ọrụ hydroxyl (-OH) nke cellulose. Mgbanwe a na-enye ethylcellulose ihe pụrụ iche, na-eme ka ọ gbazee na ihe mgbaze organic ma na-enye ikike imepụta ihe nkiri dị mma.
Àgwà nke ethylcellulose:
Mmiri: Ethylcellulose na-agbaze n'ọtụtụ ihe mgbaze organic, dịka alcohols, ketones, esters, wdg.
Njirimara imepụta ihe nkiri: Njirimara imepụta ihe nkiri dị mma, nke dabara adaba maka mkpuchi na ihe nkiri.
Ọdịdị Thermoplasticity: Ethylcellulose na-egosipụta àgwà thermoplastic, na-ekwe ka a kpụọ ya ma ọ bụ mepụta ya mgbe a na-ekpo ọkụ.
Inert: Ọ na-adịghị arụ ọrụ nke ọma n'ihi kemịkalụ, na-enye nkwụsi ike n'ọtụtụ ụzọ e si eji ya.
Ụdị ethylcellulose dị na ngwaahịa a:
1. Ọkwa viscosity dị ala:
Ọkwa ndị a nwere obere ibu molekul, ya mere ha nwere obere viscosity.
Ọ dị mma maka ngwa ndị chọrọ mkpuchi dị gịrịgịrị ma ọ bụ ihe nkiri.
Ihe atụ gụnyere ọgwụ ndị a na-achịkwa maka mwepụta na ihe mkpuchi dị gịrịgịrị na mbadamba.
2. Ọkwa viscosity dị n'etiti:
Ọkara ibu molekul na viscosity.
A na-ejikarị ya eme ihe n'ụlọ ọrụ ọgwụ maka ọgwụ ndị na-adịgide adịgide, ebe nguzozi dị n'etiti ọkpụrụkpụ mkpuchi na ọnụego ntọhapụ dị oke mkpa.
A na-ejikwa ya eme ihe n'imepụta ihe nrapado pụrụ iche na ihe mkpuchi.
3. Ọkwa dị elu nke viscosity:
Akara ndị a nwere ibu molekul dị elu, ya mere ha nwere ike ịdị elu karịa.
Ọ dị mma maka ngwa ndị chọrọ mkpuchi ma ọ bụ ihe nkiri siri ike.
A na-eji ya eme ihe mkpuchi nchebe dịka ink, agba na varnish.
4. Ọkwa dị nro:
Akara ndị a nwere obere nha nke ihe ndị dị n'ime ha, nke na-enyere aka ime ka mkpuchi ahụ dị nro ma melite mgbasa na ngwọta.
Chọta ngwa maka ink mbipụta dị elu na mkpuchi maka ịkwadebe elu mara mma.
5. Ọkwa dị elu nke ọdịnaya ethoxy:
Ethylcellulose nwere oke ethoxylation.
Na-enye mgbaze ka mma n'ọtụtụ ihe mgbaze dị iche iche.
A na-eji ya eme ihe n'ọrụ ndị chọrọ polymers dị elu, dịka ụfọdụ ọgwụ.
6. Ọkwa mmiri dị ala:
Ethyl cellulose nwere obere mmiri mmiri.
Ọ dị mma maka ojiji ebe nsogbu mmiri dị, dịka imepụta ọgwụ ndị na-emetụta mmiri.
7. Ọkwa Thermoplastic:
Ụdị ọkwa ndị a na-egosipụta ezigbo thermoplastic.
A na-eji ya eme ihe n'ịkpụzi ihe ebe ọ dị mkpa ka e mee ka ihe dị nro ma kpụzie ya n'oge okpomọkụ dị elu.
8. Ọkwa mwepụta a na-achịkwa:
Emebere ya maka ọgwụ ndị chọrọ ka ewepụtara ọgwụ a na-achịkwa ruo ogologo oge.
Emebere ya iji nweta mmegharị ntọhapụ achọrọ ma na-eme ka ọ kwụsie ike.
Ngwa nke ethylcellulose:
1. Ọgwụ:
Ọgwụ ndị a na-achịkwa maka mwepụta ọgwụ.
Mkpuchi mbadamba maka ikpuchi uto na ịgbaze nke ọma.
Ihe njide maka granules na mmepụta mbadamba.
2. Mkpuchi na ink:
Mkpuchi nchebe maka elu dị iche iche.
Ink mbipụta maka ibipụta flexographic na gravure.
Mkpuchi ụgbọala na nke ụlọ ọrụ mmepụta ihe.
3. Ihe mgbakwụnye na ihe mkpuchi:
Ngwakọta pụrụ iche maka ọtụtụ ojiji.
Ihe mkpuchi eji eme ihe maka nkwonkwo na mkpuchi n'ihe owuwu na mmepụta ihe.
4. Ụlọ ọrụ nri:
Mkpuchi a na-eri n'elu mkpụrụ osisi na akwụkwọ nri na-eme ka ndụ ha dịkwuo ogologo.
Mkpuchi nke ụtọ na ihe na-esi ísì ụtọ.
5. Plastik na Ịkpụzi:
Omume Thermoplastic na ngwa ịkpụzi.
Na-emepụta ngwaahịa plastik pụrụ iche.
6. Ngwaahịa eletrọniki:
A na-eji ya eme ihe mkpuchi nchebe maka ihe eletrọnịkị.
na ngwụcha:
Ụdị ethylcellulose dị iche iche dị maka iji ya mee ihe n'ọtụtụ ụlọ ọrụ dị iche iche. Site na ọgwụ ruo na ihe mkpuchi na ihe nrapado, ụdị ethylcellulose dị iche iche, nke ọ bụla e mere iji gboo mkpa ụfọdụ. Ka teknụzụ na ihe achọrọ n'ụlọ ọrụ na-aga n'ihu na-agbanwe, mmepe nke ụdị ethylcellulose ọhụrụ nwere ihe ndị ka mma nwere ike ịrụ ọrụ dị mkpa n'imezu mkpa nke ngwa ndị na-apụta. Ịghọta ọdịiche dị n'etiti ụdị ndị a na-enyere ndị nrụpụta aka ịhọrọ ethylcellulose kacha mma maka ngwa ha kpọmkwem, na-ahụ na arụmọrụ na arụmọrụ kacha mma.
